Getting a battery replaced (car)?

If it is just the battery it may take up to 45 minutes depending on if you have a bar across your battery that has to be taken off to get to the battery. You can just go to Auto Zone, Advanced Auto Parts, Napa, or O'Rielly's and they can do it for you. They can also check to see if it is the alternator or the battery. Most of those places also replace the battery for you and also recycle the old one. Good Luck.
